A method for making a longitudinal fold in a web, including the steps of: (1) providing a web-supporting device; (2) providing a folding belt disposed adjacent to a first longitudinal edge of the web-supporting device; (3) providing the web which is superimposed onto a web-contacting surface of the web-supporting device such that a first longitudinal edge of the web extends laterally beyond the first longitudinal edge of the web-supporting device and at least partially onto the folding belt; and (4) folding the first longitudinal fold of the web by twisting the folding belt around its longitudinal axis of rotation. The longitudinal axis of rotation of the folding belt extends parallel to the longitudinal fold line of the web.
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of the copending parent application U.S. Ser. No. 09/703,742 filed Nov. 1, 2000.
A quarter folder comprising an input conveyer for receiving a shingled stream of half folded signatures, an aligning section for aligning the signatures, a folding section for folding the shingled stream to thereby form a quarter folded shingled stream, a singulating section to separate the shingled signatures into individual folded signatures and a re-shingling section. The quarter folder of the present invention can operate at a high speed and receive copies directly from a press.
